FARMINGTON — A woman accused of stabbing a man Thursday evening at a Farmington Walmart is claiming she was trying to stop a fight involving her fiance.

Brittney Grilli, 19, is charged and accused of a third-degree felony count of aggravated battery and a fourth-degree felony count of tampering with evidence, according to court records.

She is accused of stabbing a man an unknown amount of times with a kitchen-style knife in his neck and back Thursday evening behind the Walmart at 1400 W. Main St., according to the criminal complaint.

Grilli and Daniel Hernie, 25, are also accused of discarding a kitchen knife used in the stabbing, according to court documents.

Henrie is also facing a fourth-degree felony count of tampering with evidence, according to court records.

Grilli and Hernie did not have legal representation as of this afternoon, according to court records.

The male victim was found "bleeding profusely" as store employees were applying pressure to his wounds with paper towels, according to court documents. He was transported to San Juan Regional Medical Center.

During a search of the area, officers found Grilli and Henrie hiding in a bush on the east side of the Walmart in a dirt lot.

An officer observed Henrie had blood on his shirt and when asked about it, Grilli responded Hernie had been involved in a fight with a man earlier in the evening, according to court documents.

During an interview at the police department, Grilli told police the victim and the couple had been drinking a bottle of alcohol behind the Walmart.

She added the victim and her fiance Hernie got into an argument and started fighting.

Grilli told police she observed a knife fall out of Hernie's pocket and she used it to stab the victim an unknown amount of times.

She also claimed Hernie discarded the knife later recovered by police, according to court documents.

The knife found at the scene had a dry, red substance on it, the complaint states.

Grillie and Hernie made their first appearance in Farmington Magistrate Court this morning.

She remains incarcerated at the San Juan County Adult Detention Center on no bond hold.

Hernie was released on a $2,000 unsecured appearance bond.

Their preliminary hearings are scheduled for 8:30 a.m. on Oct. 11.
